The unique steam locomotive "Fire Queen" built in 1848 by Horlocks for the 4ft gauge Padarn Railway.
Pictured outside her shed at Llanberis. [date ??? - possibly 10 Dec 1969 - but that bit of track looks very temporary]. Her "twin" the Jenny Lind was scrapped.
Moved from the National Trust's Penrhyn Castle railway museum to the Vale of Rheidol's museum at Aberystwyth in early 2024.
